Q4236 Medicaid reimbursement rate by state (2026)

• Order. States are listed from the highest published rate to the lowest. No single unit is shared by 8 or more states for Q4236, so the order is by published amount and is not a like-for-like rank.
• Medicaid rate. The most the state's fee-for-service program pays for one unit, as published. 5 of the 10 states list more than one rate for Q4236, by modifier, provider type or setting; the table shows the one that matches the provider level and setting used across states, without add-ons.
• Unit. None of the 10 schedules prints a separate unit for Q4236, so each amount is a flat payment for one service as the code defines it.
• Per hour. Q4236 is not billed in time units in these states, so no hourly figure is shown.
• Managed-care plans. The rule the state sets for its plans on this rate. What each rule means is explained below.
• % of Medicare. Medicare amounts exist for Q4236, but no state's Medicaid unit matches Medicare's billing unit closely enough to compute a percentage.
• Source and date. Each Source link opens the state's own document; “since” is the date the rate took effect.

Published rates for Q4236 run from $81.15 in Michigan to $811.51 in Ohio, a 10.0x gap in the same unit. Half the states pay more than the median of $288.34 and half pay less. The usual reasons for a spread like this in pharmacy rates:

• States differ in whether they pay a fixed fee, a percentage of a benchmark or invoice cost.
• Drugs given in a practice or clinic are commonly priced from a benchmark such as average sales price or wholesale acquisition cost, which moves every quarter.
• For children, many vaccines are supplied through the federal Vaccines for Children program, so the Medicaid payment can be for administration only.

Timing matters too. 5 states set the current rate for Q4236 in 2026 or later. A state that has not updated its rate in years will drift down the ranking as others raise theirs.

What a plan pays for Q4236 is negotiated privately, but the state decides how much room there is to negotiate. Here is how the rules break down across the 10 states.

In 5 states, plans negotiate and the published rate is a benchmark or out-of-network default. The rule for the remaining 5 states is not classified yet.

• Plans negotiate; the published rate applies out of network (5 states). In-network rates can be above or below the published rate. The published rate is the benchmark both sides know, and the fallback if no contract is signed.

Plan-negotiated rates are never estimated here. To see the rule and its citation for a particular state, open that state's managed-care page, for example Ohio managed care.

Q4236 is a HCPCS Level II temporary code in the pharmacy line, billed mostly by practices and clinics that administer vaccines and drugs. Q codes are temporary codes for drugs, biologicals, supplies and services. The unit depends on the code and is often a dose or an item.

Drug codes are billed in units of the dose stated in the code, so a larger dose bills more units. Many states require the National Drug Code (NDC) on the claim alongside the billing code.

Medicare's 2026 physician fee schedule pays $115.04–$183.51 for Q4236 (non-facility), depending on the Medicare locality. That is a useful reference point, but Medicare and Medicaid can define the unit differently, so compare only where the units match.

Before billing, confirm the rate, unit and any modifier with the state's current schedule or the plan: the amounts here are as published, not a guarantee of payment.
